Checking Member Versions in a Mixed Cluster

Checking Member Versions in a Mixed Cluster

During a rolling upgrade, you can check the current GemFire version of all members in
the cluster by looking at the server or locator logs.

When an upgraded member reconnects to the distributed system, it logs all the members it can
see as well as the GemFire version of those members. For example, an upgraded locator will now
detect GemFire members running the older version of GemFire (in this case, the version being
upgraded-- GFE 8.0.0)
